Shape tweening letters

[Black Phantom]

Hi, i'm having an annoying problem to which the solution should be simple enough, but I can't get it right...
It's regarding shape tweening letters. I want want to shape tween a 'T' so that it turns to an 'I'. However, its not working (the tweening line isnt straight, its like this: - - - -). Could anyone please help me out here? I've also tried using shape hints but no success there either.:mad:
If I do an object instead of a letter, like turning a circle into a square I can get it to work, but I'm not sure what I'm doing wrong with the letters...

ok, one quick thought...have you turned those letters into shapes? you can do that if you select the letter and press control+B. if you have a word, it would first un-group it to letters, then to shapes.

Ruban started a topic about this and Marvin Dylan posted a very nice fla as an example. Perhaps you could check that out. I beleive it is in animation and effects.
